Prevalence of diagnosed diabetes among adults in the U.S. 1997-2018

In 2018, the prevalence of diagnosed diabetes in the United States among people aged 18 and over amounted to 10.1 percent, which was the highest percentage seen since 1997. Diagnosed diabetes among U.S. adults has doubled within these last few decades.

Projected diabetes numbers

The number of adults with diagnosed diabetes is expected to increase significantly in the coming decades. While approximately 22 million adults in the United States had diabetes in 2014, this number is projected to almost triple, reaching over 60 million by 2060. People aged 45 and older are predicted to be diagnosed much more frequently in the coming decades: in 2014, under 4 million people aged 75 or older lived with the condition. By 2060, this age group is expected to have almost 20 million people with diagnosed diabetes.

Leading diabetic states

In 2018, the U.S. states with the highest prevalence of diagnosed diabetes were West Virginia, Alabama, and Mississippi, respectively. Just over 16 percent of adults in West Virginia had diabetes that year. Roughly 12.6 percent of adults in Florida had been diagnosed with diabetes before or during the measured period, putting the state of Florida in tenth place.

Supplementary notes

Figures from 1997 to 2005 were taken from the previous year's report and can be found here.

Estimates are age-adjusted using the projected 2000 U.S. population as the standard population and four age groups: 18–44, 45–54, 55–64, and 65 and over. NOTES: Data are based on household interviews of a sample of the civilian noninstitutionalized population. Beginning with 2012 data, the National Health Interview Survey transitioned to weights derived from the 2010 census. For 2006–2011 data, weights were derived from the 2000 census.
